Ruby on Debian Squeeze

irvken · 04-11-2013, 08:11 AM

I'm having some problems getting a RoR application to run on my Debian Squeeze server and I think it has something to do with the way Debian handles ruby.

Afer several attempts to install through the package manager I stripped all ruby related entries and installed RVM and then installed Ruby.

So this is where I am now, is there anything glaringly wrong here

Code:

rvm info
/usr/local/rvm/scripts/info: /usr/bin/gem: /usr/bin/ruby1.8: bad interpreter: No such file or directory

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.


system:

  system:
    uname:       "Linux irvken 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux"
    system:      "debian/6.0.6/x86_64"
    bash:        "/bin/bash => GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu)"
    zsh:         " => not installed"

  rvm:
    version:      "rvm 1.19.1 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]"
    updated:      "23 hours 37 minutes 26 seconds ago"

  homes:
    gem:          "not set"
    ruby:         "not set"

  binaries:
    ruby:         ""
    irb:          "/usr/bin/irb"
    gem:          "/usr/bin/gem"
    rake:         "/usr/bin/rake"

  environment:
    PATH:         "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/rvm/bin:/usr/local/bin/"
    GEM_HOME:     ""
    GEM_PATH:     ""
    MY_RUBY_HOME: ""
    IRBRC:        ""
    RUBYOPT:      ""
    gemset:       ""

Thanks for any advice/help/pointers in advance

Did you read what you posted?

Ah, sorry about that. I was assuming readerswould ignore the error message because I had because a) I'm running a remote bash session not a gnome terminal and b) the command runs and outputs below anyway. Perhaps I shoul;d have just posted the relevant output

Code:

On my system (Fedora 19), /usr/bin/ruby is a bash script that selects the ruby interpreter to be executed. (Either ruby-mri or jruby).

In any case, ruby1.8 seems to be a somewhat unlikely name for the system's ruby interpreter binary. (Unless Debian breaks all scripts using ruby as an interpreter command.)

In any case, note that your listing states that:

Code:

  binaries:
    ruby:         ""

indicating that you have no ruby interpreter binary installed.

(You can, I believe, execute a gem with the gem command, or by using a gem shebang in a script.)

I think you should try to reinstall gem. That gem must have been there since ruby1.8 but the system must have updated to 1.9 already. If it doesn't work perhaps you could try reinstalling rvm as well.

Edit: You could also try switching your default interpreter: https://wiki.debian.org/Ruby (take a look at ruby-switch)
